What is the corresponding sequence to CTAACG?

The corresponding sequence to CTAACG is GAGTTC. This is because DNA is a double helix, and the nucleotides on one strand always pair with the same nucleotides on the other strand. Adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G). So, if one strand of DNA has the sequence CTAACG, the other strand must have the sequence GAGTTC.
